What are the digestive physiological characteristics of donkeys?
The digestive physiological characteristics of the donkey: the donkey has hard and developed teeth and flexible upper and lower lips, which is suitable for chewing rough feed. The salivary glands of the donkey are well developed and can be softly digested by 4 times as many saliva bubbles per 1 kg of forage. The donkey has a small stomach, which is only 1/15 of that of a calf. The cardiac sphincter of the donkey stomach is well developed, while the vomiting nerve is underdeveloped, so it is not easy to feed feed that is easy to produce gas by glycolysis, so as not to cause stomach dilatation. The chyme stays in the stomach for a short time. When the chyme in the donkey's stomach reaches 2/3, with the continuous feeding, the stomach contents continue to be excreted into the intestine. The donkey's cecum is large, and the food is retained in the cecum for 18 to 24 hours, accounting for more than 1/3 of the food retention time in the digestive tract.
